Specification of Letters Patent. 1 Patented June 11, 1918..

Application filed October 30, 1916. Serial No. 128,426.

To all whom z't may concern:

Be it knownthat I, RUDOLE E. HELL- MUND, a subject of the German. Emperor,

.- have invented a new and a resident of Swissvale, of Allegheny and State of Pennsylvania, and useful Improve.

-ment in Locomotives, of which the follow xing is a specification. I

- wheels and theauxiliary:trucksthereof so lsdisposed relativeto the propelling-motors w as to; insure characteristics. t Another objectof-myfinvention isto prolnventlon relates to? locomotives and particularly to. electric locomotives of the side-rod type. 1 One object of my. invention is to provide a locomotive which shall have th'edriving good tracking. and guiding vide a locomotive of the'z-above-indicated character which "shall .have thepropelling motors thereof mounted. above the-driving wheels,-a jack shaft located? adjacentto the.

. side rods,

driving wheels and connected thereto by a rigid member connecting onepropellinglmotor .to the jack shaft and a flexible means connecting a second oneof; the. motors to the jack shaft.

-More specifically, 'my invention consists truck, and pairs of driving wheelsdisposed'" between the pivotal andthe-radial truck. A

jackshaft, islocated adjacent to the driving wheel's'and is connected thereto-by siderods.

One of the zpropelling :motors, whichis mounted abovethe-driving wheels, is -con-" nectedto the jackshaft by a. rigid member,

of the motors connected to:

In the accompanyingdrawings, Figure 1 is a partial elevational' view of a locomotive constructed in accordance with amy invenj illustrating modifications Referringto, Fig.

tion; and Figs.,2, 3 and 4 are similarviews locomotive 1 embodlesa cab2 and two artic i ;.ulated running gears Band 4, which arejoined. together by an. articulated connec-,

. 'tion; 5..

Each of the, em-p bodies side' frames 6, a pivotal outer-truck 7,-which isjoinedf to the side .framesby a.

PiYQWl pen e ticu 18, a two-wheel radial.

in the county -14 of :the

;-tothe triangular-shaped members of my invention, 1 of the' drawings, a,

truck 9 and three pairs of driving'wheels :10, .11 and 12,-which are disposed between the pivotal truck 7 and the radial truck 9.

"A jack shaft. '13,- having crank'disks 14 mounted thereon, is disposed between the pivotal truck 7 and 'the pair of driving wheels 10 and is'connected to the driving wheels 10,11 and 12 by 'means of side rods 15, 16 and17. Two motors 18 and 19, having crank disks 20 and 21, are mounted substantially above the pairs of driving wheels 10, 11 and12." The crank disks 20 of the motor 18 are connected to the'crank disks jack shaft 12 by means of'motor rods 22, and :the crank disks 21 ofthe, motor 18 are connectedfto the motor rod 22- by means of rods 23.

-. Like parts of the modified locomotives illustrated in Figs. 2, 3 and 4 will be designated by referencecharacters which conform to those used in Fig. 1 of the drawings. In Fig. 2 of the drawings, the crank disks 20 of the'motor 18 are connected to the crank disks 14 of the jack. shaft 13by means of rigid triangular shaped. members 24, and l the crank disks 21 of the motor 19 are connected to the triangular-shaped members. 24 by .means of rods 25. The locomotive illustrated in Fig. 2 differs from the locomotive illustrated in Fig. 1 essentially, in that the *motor rods;.22 of Fig. 1: are replacedby the triangular-shaped members, which are illustrated in-Fig. 2. x r;

In Fig. 3 of the drawings, the crank'disks 2110f the motor 19 are connected to the crank "disks.14 of the jackshaft' l3-by means'of rigid .triangular shaped members 26, and the crankdisks 20 of-i'the motor-18 are connected 26 by .means of motor rods 27.

t In Fig.4 of the drawings, the jackshaft 13 is mounted between the'pairs of driving wheels 10 and 12, in place of the driving wheels 11, and the crank disks 14 of the jack shaft 13 are connected to the driving wheels 29. The crank disks 20 of themotor 18, are connected to the crank disks 14 and the side -rods 28 and 29 by -means? of :.triangularshaped-members 30, :and Z the" crank disks 21 w are. connected to the triangular-shaped memz-be'rs'30 by meansof rods 31.

, In, each, of the above described locomotives, oneof'the motors isdirectly connected to a ja k glmftand theside rods of the 10m.

.100 10 and 12 by means of the side rods 28 and i motive by means of a rigid connecting member, and a second motor is connected to the jack shaft by means which is flexible. i

The runninggea'rs' of each of 'th'e above illustrated locomotives may be the cab associated therewith by the usual pivotal connection or bya connection such a's'is disclosedin the application of George M.
